Electric Tubular Resistance Industrial Cartridge Heater
Cartridge heaters is consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention. The heating wire inside which is wound onto a ceramic core.
Cartridge heaters are used for several heating metal parts and can be fitted with threaded bushings for liquid heating for certain applications. cartridge heaters will reach metal temperatures of up to 760°C with the appropriate material, watt density, and fit selections .
Cartridge heaters are made of crimped-on or swaged-in construction that consists in a high-grade nickel chromium resistance wire wound around a high-quality MgO core that is centered in a stainless steel casing.

Termination Options:
1.Swaged-in Flexible leads:
Swaged-in flexible leads, with silicone-fiberglass insulation, are recommended for applications in which the leads must be bent at the exit point from the heater.
Unless longer length is specified, 250mm (10 in.) leads are supplied.
Heaters 150mm (6 in.) or shorter generally have a 6 mm(1/4 in.) no-heat section. Heaters up to 250mm (10 in.) require a 25mm (1 in.) no-heat section. Heaters greater than 250mm may require more than a 25mm no-heat section. To order, please specify swaged-in flexible leads.
2. Right Angle leads:
Right angle leads are used in applications with a high degree of flexing and when space limitations are critical. Lead wires exit at a 90° angle through the side of the heater sheath.
Right angle tube may be necessary on certain constructions.To order, specify right angle leads and lead length.
3. Flanges
Stainless steel flanges are a convenient mounting method as well as a way to position a heater within an application. Flange style according to customer requirements. These flanges can be located in any no-heat section of the heater sheath. To order, specify flange, flange size and location.
Immersion Cartridge Heaters:
(For liquid immersion heating applications, use brass or stainless steel threaded bushing.)
The size of threaded bushing is matched according to pipe diameter. The specifications of threaded bushing include G thread, NPT thread, BSPP thread, etc.
When ordering Cartridge Heaters, please specify the following information :
1. Type of Cartridge Heater.(please refer to Termination Options)
2. Diameter of Cartridge Heater.
3. Overall length for a straight Cartridge Heaters.
4. Wattage & Voltage
5. Lead type(glass fibre / PTFE) & lead length.
